OIL BURNING BOILER Filed March-30, 1936 INVENTOR MARCO CASALE ATTORNEY Patented Oct. 27, 1936 'OIL'BURNING BoiL Eit I Marco Casale, New York, N. Y., assignor to Gasmark Corporation, New York," N. Y; N 7 Application March. 30, 1936. Serial No. 3 Claims. (01. 122-268); j

This invention relates to boilers andis directed to a boiler provided with a gun type or pressure oil burner. N An object of this invention is to provide a highly improved unitary fire pit auxiliary boiler of the character described, so constructed ,as to permit ready installation within the fire pits of existing boiler furnaces of various sizes, and connection to the main boiler, to' greatly increase the efiiciency and reduce loss of heat. N

A further object of this invention is to provide a boiler of the character described made of a single casting of cast steel or iron so constructed as to accommodate any gun type or pressure oil burner andhaving bottom, side, front and rear double walls forming a single chamber containing water directly receiving the flame from the burner to quicklyheat the same withoutsubstantial loss of heat. r Another-object of this invention is to provide an auxiliary boiler of the character described having means to collect oil drippings, andprovided with an additional section constituting a combined chamber and flame deflector which may be readily added or removed'depending upon the steam requirements. v

Yet another object of this invention is to provide a campact' and durable auxiliary boiler of the character described which may be incorporated into' new; boilersor installed in low pressure steam, hot watr'or'high pressure steam boilers now existing, which shall be relatively inexpensive to construct and install and which shall yet be practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described,

and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Referring now in detail to the, drawing, l designates a. steam orhot water boilerbr furnace provided with an auxiliary boiler embodying the invention. The boiler l0 rests upon a. cement or concretefloor H and comprisestgenerallyof a lower bas'epor. ,flre pit portionl I4, a cylindrical water jacketed portion l5, and a top: portion l6 likewise DIOVldEdIWlthB. water jacket; The door l'l-of the furnaceisinthe portion l thereof, and the bottom portion .l,4.has a: flanged opening l9 receiving the, inwardly "projecting, horizontalnozzle" 2ll of the oily burner, which maybe; of any gunor-oil pressure type. r

1 An inlet pipe 22 isconne'cted to the 'botto'mend of the-portion l5, as at 23, to. feed .cold water to the boiler. An outlet pipe '25 connected to the top of the boiler, servesa's an outlet for. the heatedwater or steam..

The auxiliary boiler 26 .embodying the inven-v tion is located within the firepit or bottom'part 5 of the boilergand rests on the floor ll Said boiler is of 7 generally prismatic shape. and is pref 4 erably made of asingle casting, either .caLstriroh or castasteel. I The same comprises a bottom pore-Y tion 2"I,,a rear portion 28, a front portion .29; and" left and right side portions 30 and;3, l. ySaid por-; tions havedouble walls togprovideaqsingle box like chamber for water. .The bottom .Wallhasa; central through opening 32 adjacent the front portion for the purpose hereinafter appearing.

The front wall 29 has a central cut out 34at the top alignedwith the flanged opening l9, to ac- I commodate the end of the burner nozzle 20.

Preferably the upper edge of the front, rear and side portions of the boiler 26 is of a higher level than the nozzle 20 so that the flames from the latterare directed into the hollow of said boiler.

The upper edge of the front wall 29, on opposite sides of the cut out 34, has an inwardly ex-' tending hollow lip 29a. forming a ledge to extend the top front portion of the boiler whereby the boiler may be used in fire pits of various sizes.

The outer wall of front portion 29 may be provided with a clean out plug 36. The outer wall of side portion 3| is provided with a pair of upper and lower nipples 38 and 39. The outer wall of the other side wall 30 has a nipple 40 adjacent the top of said wall. A pipe 4| may interconnect the bottom of jacket portion l5 with the lower nipple 39, said pipe extending through a suitable opening 42 in the portion l 4 of the boiler. v

Another pipe 43 interconnects the'nipple 40 with the top portion [6 of the boiler I0, said pipe pass-.

ing through a suitable opening 44 in the base of the furnace. The nipple 38 may be closed by a plug.

The top walls of side portions 29, 30 may also be provided with screw threaded openings 45, 46 plugged by plugs 45a, 46a, for the purpose hereinafter appearing.

It will now be understood that drippings from the burner nozzle will collect in the opening 32, and any suitable absorbent material may be placed in said opening to absorb the dripped oil.

If desired, the nipple 40 may be plugged and the pipe 43 connected to the nipple 38: Thus the pipe 43 may be located on either side of the boiler.

It will now be understood that water is fed through inlet pipe 22 to the water jacket l5. Also from said jacket water passes to the bottom of the auxiliary boiler 26 through pipe 4|. The heated water or steam passes from boiler 26 to the water jacket I6 through pipe 43 and mixes with the steam or water heated within jacket I5, thence passing to the outlet pipe 25.

In Figs. 4 and 5 is illustrated a modified form of my invention. In said figures is shown an auxiliary boiler 26. The plugs 45a, 46a are removed however and upstanding pipes 50, 5| are screwed to the openings 45, 46. Mounted on said pipes is an additional section 53 comprising a hollow, horizontal ribbed jacket provided on the under side thereof with openings to which the upper ends of the pipes 50, 5| are screwed. Said jacket or section 53 is preferably provided with a pair of plugged openings 54, 55 on the top surface thereof. When the additional section 53 is utilized, the nipples 38 and 40 are plugged and the pipe 43 is screwed either to the one or the other of the openings 54, 55 depending upon which side of the boiler it is desired to locate said pipe.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the condition of practical use.

'As various embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
